What is a technical disclosure document? How to write a technical communication letter

The provision of technical communication documents is generally applicable to applications for utility models or invention patents. When applying for a design patent, it is generally not necessary to provide a technical briefing document.

The technical briefing document is the technical information provided by the applicant to the patent agent. It is a written material that reflects the technical content of the invention or utility model. This technical information is the basis for the agent to write the application documents. The technical information is The content should include the name, the technical field involved in the invention or utility model, the background technology related to the invention or utility model, the content of the invention, the drawings and their descriptions, and practical examples of the applied technology.

Explanation: "Technical briefing" is a reference document for the inventor to submit the content of the invention to be patented to the patent agency in written form, making it easier for the patent agent to understand the characteristics of the inventor's invention. ; A comprehensive and compliant technical disclosure document will help improve the quality and efficiency of patent application document writing by patent agents and better fight for the rights and interests of inventors.

The elements listed below are essential for patent application documents. The inventor is required to write an electronic text to the patent agency based on the content of the invention and refer to this format and requirements. The number of words in brackets is Suggestions are for reference only.

Elements and writing requirements of the "technical briefing document" for a patent application for an invention or utility model

Name of the invention or utility model (number of words: within 25)

Requirements: Briefly and accurately indicate the subject matter and type of protection claimed by the invention or utility model patent application.

Technical terms commonly used in this technical field should be used, and made-up non-technical terms should not be used. People's names, place names, trademarks, models or product names should not be used, and commercial promotional terms should not be used; such as "a kind of XXX style faucet".

(1) Technical field (number of words: within 100)

Requirements: State the technical field to which the technical solution requested to be protected belongs.

Refers to the technical field to which the invention directly belongs, for example: "The present invention relates to a valve device, especially to an XXX type faucet."

(2) Background technology (Word count: 500 or more)

Requirements: State the background technology (existing technology) useful for understanding, retrieval and examination of the invention or utility model; if possible, cite documents reflecting these background technologies. .

To be specific, it is to cite the 1 to 2 most relevant domestic and foreign existing technologies that are useful for understanding, retrieval and examination of the invention or utility model, which can be based on the purpose, technical measures (or composition) It will be described from three aspects of the invention and the effect, and the problems and shortcomings existing in the prior art will also be pointed out objectively, but it will be limited to the problems and shortcomings solved by the technical solution involving the present invention or utility model. For example, inventing a "back chair" with a "stool" as the background technology (existing technology) is to point out the problems and shortcomings of the "stool", such as sitting for a long time without the convenience of leaning on it. For this reason, it is necessary to invent a chair. A kind of "back chair" or even "back chair with armrests" that can solve these problems and provide comfort and convenience. Of course, in fact, these technologies already exist in real life.

If the cited document is a patent document, at least the country and publication number must be stated, preferably including the date of publication; if it is a non-patent document, such as journals, magazines, manuals and books, etc., it must be stated Indicate the titles and detailed sources of these documents, such as the title, author, publisher, edition and page number of the book, and the name, volume number, issue number and page number of the journal. If the most relevant prior art is not yet clear, a literature search can be commissioned by a patent company.

(3) Invention content

Requirements: including the technical problems to be solved by the invention or utility model, technical solutions and beneficial effects.

Technical problems to be solved (number of words: more than 200)

Requirements: Explain the technical problems existing in the existing technology to be solved by the invention or utility model.

When writing specifically, use positive, concise language as possible to objectively and well-founded reflect the technical problems to be solved by the invention or utility model in view of the defects or deficiencies existing in the existing technology. You can also further explain it. Its technical effect, but avoid directly using general words such as "saving energy" and "improving quality", and do not use advertising terms.

Technical solution (word count: 800 or more)

Requirements: Clearly and completely describe the technical features of the technical solution adopted by the invention or utility model to solve the technical problem.

Specifically, the technical solution created by the present invention will be elaborated in detail and shall be explained in conjunction with the accompanying drawings. The content of the description should be understandable by those skilled in the technical field; note: do not only refer to a specific embodiment, that is, a point, but should be written as a technical solution to solve the problem, that is, a range. For example, the shortcomings of a round pencil (assuming it is an existing technology) are that it is easy to roll and the lead is easy to break. To solve this problem, it is certainly possible to "improve" it into a six-sided pencil (assuming it is the content of the invention). , but this is just an example of implementation, that is, a shape selection, written as a technical solution, there can be more shapes to choose from, best described as "polygonal pencil", in this technical solution can include six-edged , triangular and other shapes, this constitutes a range. However, do not expand this range without limit. The principle is not to include existing technologies; this part must echo the previous purpose and the subsequent effect, and be consistent with the previous purpose and the subsequent effect. The claims are corresponding; after the application documents are submitted to the patent office, the claims can be modified, but the content of the description cannot be substantially modified or added. Therefore, the description in this part must be clear, complete, and accurate.

Especially for the inventive points of the present invention that are different from the prior art, the description should be as clear, accurate, and complete as possible to the extent that a person of ordinary skill in the art can implement it, and each technology should be described When a means is used, its role in the present invention will be described accordingly. Specifically,

1) If the invention is a structured product, the composition or structure of the product, the location of each part, the relationship between parts, raw materials, specifications, parameters, and principles need to be pointed out and uses, etc.;

2) If the invention is a method, it is necessary to point out the process flow, steps, raw material composition and formula, process parameters, product standards, detection methods and experimental results, etc.; the formula and parameters are the most It is best to use range expressions, such as the components of the formula and the content of each component (weight percentage or parts), in order to strive for the maximum protection scope. If chemical raw materials are involved, the specific chemical name (molecular formula) must also be given.

Beneficial effects (number of words: 200 or more)

Requirements: Clearly and objectively describe the beneficial effects of the invention or utility model compared with the existing technology. Generally speaking, beneficial effects can include improvements in productivity, quality, precision and efficiency, savings in energy consumption, raw materials, and processes, ease of processing, operation, control, and use, treatment or eradication of environmental pollution, and the emergence of useful properties.

Requirement: The specific implementation mode of the present invention or utility model will be described in further detail with reference to the accompanying drawings.

This part should give the best implementation plan of the invention and creation, which is the embodiment of the technical solution. The required content is very specific. All formulas and parameters are usually a specific point (rather than a range) , the embodiment may be one or multiple. The more embodiments, the more conducive to obtaining a wide range of protection. Generally speaking, this part should at least specifically describe one best implementation mode. Sometimes an embodiment can be understood as a detailed record of an experiment. Changing one or more raw materials, or changing one or more experimental parameters and doing another experiment is another embodiment. The level of detail of the examples is similar to that of a student experiment textbook, and should be clear enough that a person of ordinary skill can repeat the instructions after reading them.
